The Schedule referred to these Letters Patent and making part of the same.

To all whom it may concern.- 7

Be it known that-I, T. D. SIMQNTOX, of St. Paul, in the county of Ramsey, and State of Minnesota, have invented a new and improved Pocket-Stereoscope; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specification. 1

This invention relates to a new and useful improve ment in stereoscopes, whereby they are made much more convenient and useful than they have hitherto been; and consists in so forming the instrument and arranging the parts, that the instrument is made so as to become the receptacle of the card views,- thereby enabling the owner to pack the instrument and pictures other purposes, as will be hereinafter more fully described. I

In the accompanying drawings-'-' Figure 1 represents a longitudinal vertical section of the instrument through the line a: a: of fig. 2.

Figure 2 is a top or plan view.

Similar letters of reference indicate like parts.

A'is the case, which is a rectangular-shaped open boxpvith a covering at the vision-end, or over the lenses, as seen at B. In width and lengththe box is sufficient to accommodate the vision, and to obtain the true focal distance.

\Vheu thedepth is sufiicient to admit and secure the lenses in the end, it is suflicieut to hold a good number (twenty or thirty) stereoscopic views or cards. To make room for the views, the slide to which the view is attached is (in shape and size) made to correspond with the inside and back end of the box,.and while it also slide back tothe end, so as to take up no important amount of space.

G represents this adjustable slide. To hold this slide in place, there are small grooves in its'sides, so that, in moving back and forth, it slides on small barstrips cl, attached to the sidcs of the box. The picture is secured in slots in the sides of the slide, as seen in the drawing. v

E represents the partition for dividing the views. This is a flexible plate, secured to the bottom of the case or-box. so that it may be drawn back or forward. It is jointed or made so flexible that it may be raised so as to rest at one end on the covering 15, as seen in fig. 1. \Vhcn it is not in use, it is moved back and laid flat on the bottom, so that it. does not interfere with the views when they are packed in the case.

F F represent the lenses.

\Vhen the adjustable slide 0 is shoved backto the end of the box or case, and the partition E is laid flat on the bottom of the case, any suitable number of pictures or stereoscopic views may be laid imthe case, one end of which would beheld in place by the cover B, while the other end would be held by the elastic band -(lr, thus embracing, in one compact package, a perfect and convenient instrument and a. goodly number of views.

The advantages of this arrangement for touristsand others are many, and must beobvious to all.

Having'thus described my invention,

I claim as new, and desire to secure by Letters Patent 1. A stereoscope instrument, consisting of the case or box A, adjustable slide C, and flexible partition E,

all arranged substantially as herein described, for the purpose specified.

2. The folding partition E, arranged to slide upon the bottom of the case A, and to be supported when in use by the cover B, substantially as described, for the purpose specified.

The above specification of my invention signed by me, this 4th day of November, 1868.
